Requirements
Before connecting to AC mains power,
make sure that the mechanical installation,
wiring, cooling requirements, and controls
are all set to the configuration needed for
your particular application. Failure to do so
could result in damage to the unit or to other
components in the system.
2.1
AC Mains Requirements
This amplifier will auto-detect AC mains voltage
from 100-240VAC, 50-60Hz. At nominal 120VAC
mains, the allowed operating range is 85-
135VAC to allow for brownouts or power surges,
and for nominal 240VAC operation the range is
170-265VAC. Use only the provided AC cord to
connect to AC mains. The power consumption
is indicated on the back panel near the AC inlet.
To reduce the risk of ground loop hum, all sound
system ground references should originate at the
same AC power distribution point. Do not lift or
remove the amplifier power cord ground pin.
